Press Brake Tonnage Calculator

Instructions: Input data into the required fields for your material and punch & die configuration. This estimates the tonnage required to complete a 90° bend. (Yield and Tensile Material chart below)

Bend Radius - Outside
Estimated Air Bend Radius

Minimum Between Bends
Minimum Leg Length for Die Width

DISCLAIMER: Actual bending force is affected by many factors such as friction between the material and the die, material thickness, material strength variations, rolling direction of the steel, work hardening and other parameters. This estimator calculates a force representative of the pressbrake requirement for air bending. Sizing of a machine or available die width should allow for up to 20% additional capacity. We make no guarantee of actual force required to make a bend in a specific part.
